Access to safe water and sanitation is a major challenge in developing countries, with millions of people lacking access to basic services.

There are a variety of water treatment technologies available that can help address this issue, including point-of-use (POU) devices, filtration systems, and solar disinfection methods.

Successful implementation of water treatment technologies in developing countries requires careful consideration of factors such as cost, cultural norms, and community involvement, as well as ongoing monitoring and maintenance to ensure long-term sustainability.
